Documenting Problems That Were Difficult To Find The Answer To

Firefox Settings

When I install a new Firefox profile there are some settings I prefer.

No Addon Validation

From 2019-05-03 Mozilla realised something had gone wrong when every addon was disabled for every Firefox user. This disabled every privacy protection addon exposing browsing history unexpectedly and without warning.

Needless to say, I never want to let Firefox do this to me again.

  • navigate to about:config
  • set xpinstall.signatures.required to false

Allow Filename Choice When Saving Link

When I download a file I want a dialog to open that lets me choose the name of the file being written to.

  • Open the hamburger icon (3 horizontal stripes) for the menu and choose Preferences, or
  • Press alt-E (for the Edit menu) and select Preferences
  • find Downloads and choose the radio button “Always ask you where to save files”

Disable Service Workers

For some reason I do not understand – a new feature was added called “Service Workers” and it allows a website you visit to install a JavaScript program that runs in the background of the browser intercepting network traffic to/from that website.

Well – Twitter constantly throws up the error message “Corrupted Content Error”. Presumably because developers at Twitter have absolutely no idea how to write working code. But disabling Service Workers helps cut down that message – and are not needed at all for web browsing.

  • navigate to about:config
  • set dom.serviceWorkers.enabled to false
